Emily Blunt and her husband John Krasinski continued their holiday prank war against their close friend and neighbor Jimmy Kimmel. During "Jimmy Kimmel Live!" on Monday night, December 15, the host showed some clips of their pranks.

"You probably know Emily is married to John Krasinski," Jimmy told the audience, "John and Emily, not only are my wife and I very good friends with them, they're our neighbors. We live right across the street from each other. We have a holiday tradition that was started by them a few years back."

Jimmy said the prank war started three years ago when Emily and John broke into his house, with an extra key he had given to them, and left a Santa and Snowman light display. The host then returned the favor by installing a big neon insurance sign on the wall of the couple's driveway.

One year later, Emily and John planted a zombie in Jimmy's garden. Jimmy then placed a 26-foot tall inflatable reindeer complete with real reindeer poop in front of the couple's house as a revenge.

The next year, Jimmy planned to end the prank war by wrapping Emily and John's house in wrapping paper while they weren't home. When John came home from work, he was greeted by carolers and fake snow.

However, the prank war didn't end there. Last week when leaving from work, Jimmy found out that his car in the parking lot was covered by wrapping paper along with a tag which read, "From Your Secret Santa." After taking a selfie with the wrapped car, Jimmy tore the wrapping paper and discovered that his "whole" car was "filled with baubles."

When Emily joined him at the studio, Jimmy continued his story. "The next night, after my car was filled with ornaments, I went out to the parking lot, and this happened," he said, bringing up a video of himself heading to the parking lot. "Oh no, again?" he exclaimed after knowing that his car was wrapped again, "Unbelievable."

When trying to tear the wrapping paper, Jimmy jumped back because there were carolers inside the car. As the carolers sang "Hark! The Herald Angels Sing", a real reindeer joined them.

"Not only were you terrified, and I love that you flinched... that was the best bit ever," Emily told Jimmy, "But that, it is your nightmare - people singing at you." He then replied, "Yeah, people singing right at me is uncomfortable for me. By the way, I want to thank you for not putting the reindeer in my car."

Emily told the host that the prank didn't stop there. John then appeared wearing a Santa costume dancing in front of Jimmy's car which was once again wrapped with wrapping papers. John said he would use Jimmy's car to give away his belongings including a clarinet and a computer. He then drove the car and crashed its front and back part. There's also a piano dropped on Jimmy's car.
